Description

{Plasma Hair-Comb}

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a hair growth plasma generating apparatus, and more particularly, to a plasma generating apparatus for promoting hair growth.

Hair loss of the scalp is known to cause a variety of reasons. Genetic factors, changes in hormone secretion, and aging. In addition, it is caused by local blood circulation disorder, mental stress, nutritional imbalance, and excessive scalp bruising. For the treatment of hair loss, either ointments or oral ointments such as minoxidal are used. The drug is to block hormone conversion. In addition, there is a shampoo containing copper for preventing hair loss, and hair tonic is said to have some effect.

On the other hand, scalp massage, infrared irradiation and the like are widely used in hair loss clinics, and these procedures improve blood circulation of the scalp and improve hair loss. Hair loss management is mainly focused on therapies that remove excess keratin on the scalp and facilitate blood circulation to the scalp.

Accordingly, hair loss treatment using a medical device is performed as follows.

Meso therapy is performed by injecting meso drugs into hair follicles, and laser, LED light therapy, and fine needle aspiration induce hair growth effects. These procedures induce effects such as temperature rise of subcutaneous layer, expansion of microvessels, promotion of blood circulation, and improvement of tissue regeneration ability.

On the other hand, plasma has various sterilizing effects in addition to regeneration effect of skin tissue by activation of skin cells. In addition, the generation of plasma in the atmosphere can be facilitated by a Dielectric Barrier Discharge (DBD) method using an AC type high voltage.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

Generally, the generation of plasma for application to the skin of the human body is in the form of a plasma jet type and a dielectric barrier discharge (DBD).

A plasma jet is a method in which various kinds of gases are injected into a device and a plasma is generated by a high voltage and irradiated to the skin. This method requires a separate gas tank for the gas to be injected and requires replacement of the gas tank by the consumable gas, making it difficult for the general public to use at home.

In contrast, the dielectric barrier discharge method is a method of generating plasma on the skin in an atmospheric state without using a separate discharge gas, and therefore, an expendable part is not necessary, so that it is easy to use by the general public. Therefore, the present invention constitutes the latter plasma comb. That is, a DBD plasma source, which can be operated by discharging plasma using an atmospheric air as a discharge gas, is provided in the form of a hair comb, without a separate gas supply device.

In applying the plasma generator to the head, it may be difficult to generate plasma due to hair. The hair is also a factor that makes it difficult to use the plasma processing apparatus.

Thus, in this embodiment, plasma is generated on the scalp by applying DBD plasma. That is, in a standby state, a dielectric barrier discharge type plasma generator is formed in the form of a hair comb so that a discharge electrode is disposed for each comb, and the counter electrode is a scalp itself.

According to the present invention, by using the same plasma generating device as the hair comb and using the hair combing method, plasma can be generated on the surface of the scalp, that is, the tip of the comb and both ends of the scalp, and the plasma can be treated on the scalp.

Hereinafter, the configuration will be examined in more detail.

1 (a) and 1 (b) show a DBD plasma generator implemented with individual combs constituting the plasma comb 100 of the present invention. That is, FIG. 1 (a) shows a linear metal electrode 110, a dielectric layer 130 surrounding the metal electrode 110, and a power source for applying a voltage to the electrode 110.

As the material of the electrode 110, gold, silver, copper, nickel, aluminum and the like, which are metals with good conductivity, can be mentioned. The dielectric layer 130 may be made of high-voltage resin or the like. The thickness of the dielectric layer 130 should be selected to an appropriate thickness so as not to cause dielectric breakdown due to high voltage and to maintain electrical safety.

In the DBD plasma generator of such a configuration, the opposite electrode to the electrode 110 to which voltage is applied is not separately provided, and the scalp 120 itself acts as an opposite electrode. Thus, the plasma is discharged from the electrode 110 and the scalp 120, and the plasma treatment effect on the scalp 120 becomes very reliable. The plasma generator shown in FIG. 1 (b) bends the electrode 110 into a U shape unlike FIG. 1 (a). This 'U' shaped electrode 110 structure has the advantage of forming a wider plasma discharge region.

FIG. 2 (a) shows an embodiment of the plasma comb 100 of the present invention, and these combs are composed of the electrodes of FIG. 1 (a). It is preferable for the user's convenience to draw the electric wire to the rear end of the handle of the plasma comb 100 for applying the voltage.

2 (b) has the same structure as that of FIG. 2 (a). However, the expanding portion 170 is further provided for the purpose of widening the end surface area of the comb teeth contacting the scalp. Such a configuration can increase the amount of plasma to be treated on the scalp 120, thereby improving treatment efficiency.

The plasma comb shown in FIGS. 2 (a) and 2 (b) can be fabricated by forming a comb-shaped skeleton with a conductive metal material and applying a dielectric material to the entire metal skeleton. Connect the AC power to the metal electrode through the handle of the comb for user convenience.

3 is a cross-sectional view showing the configuration of the plasma comb 200 in which the U-shaped electrode 210 of FIG. 1 (b) is applied to a comb. The comb body 220 is formed of a nonconductive body, and the individual combs are wound by the U-shaped electrode 210 or the U-shaped electrode 210 is embedded in the comb body. The plasma comb 200 has a plurality of combs including a U-shaped electrode 210, and the U-shaped electrodes 210 are connected to each other (as will be described later with reference to FIG. 5) And the electric wire drawn out from the end of the handle 250 of the comb is provided with a plug so that it can be connected to the outlet arranged in the general building via the DC-AC inverter 270. [ The inverter normally uses a DC voltage of several volts to several tens volts as an input power source. Therefore, when using the household power supply (AC 60 Hz, 110 V or 220 V), use the adapter to convert the household AC voltage to DC voltage and use it as the input power of the inverter. When the above device is used as a portable device, the DC power is directly supplied to the inverter. In addition to regular primary batteries, batteries can be recharged to avoid the hassle of battery replacement.

More detailed cross-sectional views are shown in Figs. 4 (a) and 4 (b) for better understanding of the configuration and arrangement of the U-shaped electrode 210, The U-shaped electrode 210 and the wiring are separately shown for easy understanding of the structure wound on a plurality of combs.

4 (a) is a cross-sectional view (cut along the line A) in which the middle of the comb is cut. In the state where the metal electrode 110 is surrounded by the dielectric layer 130, that is, a 'U' shaped electrode 210 Sectional view showing a state in which the comb body 220 is wrapped. The grooves formed on both sides of the comb tooth body 220 show that the 'U' shaped electrode 210 is positioned to stabilize the position. However, such a home is not essential.

4 (b) is a cross-sectional side view of the comb tooth body 220 taken along the vertical line B. FIG. The 'U' shaped electrode 210 surrounds the body 220 of the comb and forms a U shape. The U-shaped electrode 210 is formed on the upper end of the comb body, that is, at the end to which the comb is connected, through the U-shaped electrode 210, Holes are formed on the surface of the substrate. Accordingly, the U-shaped electrode 210 may be formed of a single wire, and the whole comb may be wrapped around the single comb body 220 by passing through the holes and surrounding the comb body. FIG. 5 illustrates how the wires are arranged in a manner so that the 'U' shaped electrode 210 passes through the comb teeth bodies. This structure is safe because the U-shaped electrode 210 itself is covered with the dielectric layer 130 and is intended to further improve the plasma treatment effect.

5 shows the overall configuration of the 'U' shaped electrode 210. FIG. The 'U' shaped electrode 210 can be constructed using a commonly available high voltage coated wire. Since each U-shaped electrode has a U-shaped electrode, the U-shaped comb is bent with a long enough length of the comb to form a U-shaped comb, and then the U- Through the hole, it bends the next comb into a "U" shape. Repeat this process to cover all the combs. As a whole, it looks like a helical coil, and when it reaches the front comb, it bends to form a "U" shape and then returns to the starting point of the wire and merges with the wire of the starting point. AC inverter 270 after the metal electrode 110 inside the covering dielectric layer 130 is short-circuited and connected to the electric wire, and the DC-AC inverter 270 is connected to the DC- The end of the wire drawn out from the wire 270 is provided with a plug. That is, this configuration satisfies that a high-frequency high-voltage power source is required as an applied voltage required for plasma discharge, and it is intended that a plasma comb can be used even in a general household.

That is, the AC type high voltage is applied to the U-shaped electrode 210 to generate plasma at the contact portion with the scalp, and the plasma is a streamer-type DBD plasma generated in the atmospheric state.

The alternating current power supply preferably provides a pulsed or alternating current mode such as sine wave and sawtooth, the frequency may be from several tens of Hz to several hundreds of kHz, and the magnitude of the voltage may be from hundreds of volts to several kV. The frequency may be 1 Hz to 1 MHz, and may be 100 V to 1 MV.
Generally, the higher the frequency, the lower the voltage is. The power source for generating the AC voltage is preferably a DC-AC inverter. The inverter converts an ordinary household power supply to a DC having a constant voltage, converts the DC voltage into an AC voltage having a constant frequency in the inverter, and applies the AC voltage to the electrode 110 inside the comb.

6 is a form of a plasma comb in which a high-voltage coating wire is exposed only in a certain region of the comb end, and a wire is buried in a comb-free portion where the comb is not in contact with the scalp. That is, a 'U' shaped electrode is embedded in the comb tooth body, and the electrode end is exposed to the outside of the comb tooth body, thereby forming a plasma comb.

In addition, the method of wrapping a comb with a combed wire to realize a plasma comb can be varied in various ways of changing the path of the coated wire.

The present invention is only a few examples. It is possible to make various shapes of hair comb in the same concept. It is possible to adopt various materials other than conductors such as a comb material including a covering effect of a dielectric layer by embedding in the form of wrapping around the comb. All of which fall within the scope of this invention.
